Emergency Planning and Community Right-to-Know Act (Non-Section 313) Regulations and Amendments

Title III of the Superfund Amendments and Reauthorization Act (SARA Title III) was signed into law by Congress on October 17, 1986. SARA Title III is commonly known as the Emergency Planning and Community Right-To-Know Act (EPCRA). This Act revised and extended the authorities established under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA), which is commonly known as “Superfund.” EPCRA established authorities for emergency planning and preparedness requirements and community right-to-know reporting. This page provides links to the current regulations and statutes, a table to help identify the regulation and United States Code (U.S.C.) section for each EPCRA section, and a chronological history of the EPCRA (non-section 313) regulations and amendments.

For information on EPCRA Section 313, see EPCRA Section 313, Toxics Release Inventory Laws and Regulatory Activities.

In addition, amendments to CERCLA Table 302.4 - List of Hazardous Substances and Reportable Quantities affects EPCRA section 304 emergency release reporting requirements. See Reportable Quantities Federal Register Notices.

Advance Notice of Proposed Rulemaking for Reporting Air Releases of Hazardous Substances from Animal Waste at Farms under EPCRA

On November 9, 2023, EPA Administrator Michael S. Regan signed an Advance Notice of Proposed Rulemaking to solicit comment and information on reinstating the reporting requirements for animal waste air emissions at farms under EPCRA. EPA is seeking information on how to promote compliance and accuracy in reporting, how to streamline reporting requirements, a potential small farm exemption, and user needs for a reporting instrument, including identifying when reporting would be required.
